DBpedia's information source is Wikipedia, so it certainly isn't open to "all kinds of data."

"All kinds of data" as in sourced or unsourced. Some data in Wikipedia is not sourced.

Hoi,
In my opinion is Wikidata a collection of assertions. By providing sources respectability is provided to assertions it does however not provide certainty to what is asserted and consequently does not make them facts by definition.

It does not, but I don't think the aim is to collect all the assertions found in Wikipedia either. Remember that Wikipedia is not a primary source.

Cheers,
